CARRY stands for health and sustainability. That's why the lid is also made from materials that meet our quality standards and are good for us and our environment: The screw cap, made from biodegradable wood fibers as well as recyclable and pollutant-free polypropylene (PP), ensures comfortable handling when opening and closing the water bottle. Thanks to the silicone sealing disc inside the cap, it fits seamlessly onto the bottle. This keeps the water bottle leak-proof - even with carbonated drinks. All materials of the cap are free from plasticizers and bisphenols (BPA).
